Given numbers are 315,158,781,817,634
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 315,158,781,817,634 is 10066998255930.
Find LCM of 315,158,781,817,634 with Prime Factorization
| 2 | 315, 158, 781, 817, 634 |
| 315, 79, 781, 817, 317 |
Multiply the prime numbers at the bottom and the left side.
2 x 315 x 79 x 781 x 817 x 317 = 10066998255930
Therefore, the lowest common multiple of 315,158,781,817,634 is 10066998255930.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
315 x 158 x 781 x 817 x 634 = 20133996511860
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
315 : 1, 3, 5, 7, 9, 15, 21, 35, 45, 63, 105, 315
158 : 1, 2, 79, 158
781 : 1, 11, 71, 781
817 : 1, 19, 43, 817
634 : 1, 2, 317, 634
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 315,158,781,817,634, is 1.
Now, the common factors can be found like this.
315:3x 3x 5x 7
158:2x 79
781:11x 71
817:19x 43
634:2x 317
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2 = 2
Therefore, the value for common factors is 2.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 20133996511860/(1x2)
LCM = 20133996511860/2
LCM = 10066998255930
Thus, we can understand that the LCM of 315,158,781,817,634 is 10066998255930.
